Extracting copper from copper(II) carbonate

Malachite is a copper ore consisting mainly of basic copper(II) carbonate, CuCO3.Cu(OH)2. In this experiment, students learn how to produce copper from copper(II) carbonate by heating it to produce copper(II) oxide, which is then reduced to the metal using carbon as a reducing agent. If possible, show the class a genuine sample of malachite ore and artefacts, such as

Researchers Uncover Copper’s Potential for Reducing

18/02/2016 When used as a part of a promising coal combustion technology known as chemical looping, copper can help economically remove carbon dioxide (CO2) from fossil fuel emissions. In traditional power plants, coal is pulverized and then burned in air to create the steam that powers electricity-producing turbines. In chemical looping, the fuel (pulverized coal or natural

They are reduction of the ore with carbon, reduction of the molten ore by electrolysis, and reduction of the ore with a more reactive metal. Extraction using carbon. Metals such as zinc, iron and copper are present in ores as their oxides. Each of these oxides is heated with carbon to obtain the metal. The metal oxide loses oxygen, and is therefore reduced.

Smelting

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
